LOS ANGELES - Sony films including the Brad Pitt war movie Fury leaked online over the weekend following a cyber-attack on the studio's computer network last week.
Other films including the yet-to-be-released Annie, starring Quvenzhane Wallis, Cameron Diaz and Jamie Foxx, as well as Still Alice, starring Julianne Moore, were also shared on file-sharing platforms over the Thanksgiving break, according to reports including one from Bloomberg News.
Another film which leaked, Mr Turner - starring Timothy Spall - might have also been stolen following the Nov 24 cyber-attack.
Before the Sony computer screens went dark that Monday, they displayed a red skull and the phrase "Hacked By #GOP," which reportedly stands for Guardians of Peace, the Los Angeles Times said.
Sony Pictures is investigating to determine if hackers working on behalf of North Korea might be responsible for the attack that prompted it to shut down some of its computer systems.
The attack occurred a month before Sony is to release the Seth Rogen movie The Interview on Dec 25.
The comedy, also starring James Franco, is about two journalists who are recruited by the CIA to assassinate North Korean leader Kim Jong Un.
The Pyongyang government had denounced the film as "undisguised sponsoring of terrorism, as well as an act of war" in a letter to United Nations Secretary-General Ban Ki Moon last June.
The remake of the 1982 Annie is Sony's next big film release, to open on Dec 19, said Bloomberg.
Mr Turner and Still Alice are said to be possible Oscar contenders for their lead actors.
